STAN D LAMP.

Application tiled January 16, 1920.. Serial No. 351,804.

To all 'whom it may concern.'

Beit known that I, ItnUnN B. BENJA- MIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Stand Lamps, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part oit' this specification.

My invention relates to stand lamps, and more particularly to a cluster type stand lamp. l

Une object of my invention is to provide a stand lamp wherein an improved light dis tribution is obtained.

Another object of this invention is to provide a stand lamp wherein the switch mechanism, contacts and binding terminals are enclosed .within an ornamental casing thereby providing a neat and compact arrangement of parts.

Another object is to provide a stand lamp comprising an inverted translucent bowl having an electric light bulb therein Whereby a diused light may be obtained when desired.

Another object oit' this invention is to provide an improved construction whereby different lighting eii'ects may be obtained.

` Other objects will appear in the detailed description to follow and from the append ed claims.

Fig. 5 is a sectional detail taken on the line 5-5 of Fig. 2; and Fig. 6 is a sectional detail taken on the line 6-6 of Fig. 3. Y

In order to give, a generalv idea of the invention, it is here lstated that the construetion shown comprises a lamp pedestal 10 upon which isA disposed a metal basesuporting member 11 which supports. an 1nsuating base 12. Secured to the insulating insulating base 12.

base'12 is a conducting and supporting meniberl 13, preferably a sheet metal stamping, which has'disposed therein a plurality of shell receptacle contact members 14 upon which members 14 are threaded insulating bushings 15.

An ornamental casing 16 surrounds the metal base member 11 and the insulating base 12.y This casing is divided, the lower portion thereof being clamped between the pedestal -10 and the metal base member 11. The upper portion of said casing is apertured to receive the insulating bushings which 1bushings hold the upper portion ot the casing in place. Y l

Securely held Vbetween one of said bushings 15 andthe ornamental casing 16 at one of the apertures therein, as shown at 17, is a bowl supporting member 18in which is disposed an inverted,translucent bowl 19. Supported on said bowl by means of a plurality of clip members 20 is a suitable lamp shade 21.

To give a more detailed description of my construction, the .pedestal 10 has an axial opening 22 therein, in which opening is disposed a pipe 28. -This pipe 23 is threaded into the metal base 11, as Ishown at24, thereby securely-holding the base member 11 on the pedestal 10.4 Suitable conductors 25 and 2G pass up through said pipe 23, conical recess 27 andinto a recess Y28 in the therefore, due to said conical'recess 27 and said recess 28 given ample space in which they may be supported and secured to their respective binding kterminals and also to prevent short circuiting of the conductors.

The lower portion ot the ornamental cas ing 16 has an inwardly extending flange 29 thereon which is clamped between the ped-4 estal 10 and the metal base member 11. Said .casing also has an upwardly extending annular `flange 30 formed integral therewith within which said insulating base rests to position same on said metal base member.

The insulating base 12 has the cylindrical recess 28 extending from its lower face through which the conductors 25 and 26 pass.' An arcuate slot or recess 31 extends also from said lower face of the insulating base 12 and has disposed therein the conductor bars 32and 33.

The metal stamping conducting 'member k13 has a plurality of horizontally disposed rihe conductors are,` l

flange portions 34 thereon through which portions pass the screws thereby securing said member 153 to ,the insulatingv base 12 (Figs 2 and 5). The conducting ineinber 13 has thi-ce. radially extending portions which slope downwardly at 36 and terminate in said tiange portions 34. These downwardlysloping portions are apertured and have' secured thereto at each opening therein one of the threaded shell receptacle contacts 14. y A fourth shell receptacle con tact is disposed in a vertical axial plane on said conducting member in the same mam ner as the shell contacts on the sloping.,r portions. 1

' The switch mechanisms in this construction is of' the pull cliain'type which are suitably disposed in recesses therefor in the in sulating base 12. v.The switch mechanism hcreimhoweyer, forms no part of the inventio'n.v

The switches being ident ical. description of one will sniiice. The. switch mechanism comprises a vbrush l@tiri-'ier' 37 which is mounted on and is rotatable with a switch shaft 38 which shaft is rotatably mounted at one end in a slot 39 therefor in the insulating base and isv rotatable at its other end in an upwardly extending portion 4() which is formed integral `with a binding1 plate 4-1 (Fig. 5)., A brush member 42 is carried by said bri'ish carrier 37 which lia-s connected therewith an arm 43 whiei. engages said upwardly extending arm 40 and the Switch shaft 38 thereby electrically connecting the binding plate fifi and the brush 42. A disk or barrier 44 is also moiinted on the switch shaft 38 to which is secureda chain rail 45V upon which is mounted a pull chain t6. The chain rail 45 has a `hook member 47 formed integral therewith which engages one of the balls of the pull chain whereby the chain is secured to the chain rail. The insulating base 12 and the metal .base member 11 are recessed at 4S to allow a passage for the downwardly extending portlon of the pull chain in which recess isdisposed an eyelet 49. The pull chain has disposed between two balls thereof a cup-shaped stamping 50 which s-tapered to enter the e elet 49. Saidcup-shaped member 50 is slightly larger than the opening in said cyelet and therefore cannot pass therethrough bnt will act as a stop for the pull chain to limit the travel of the brush earrior. A projection 51 (Fig. (i) on the insu? loting base also limits the travel of the brush carrier by being Iengaged by the hook tmemberf? on the chain rail.

The switches are electrically corinecte'd'by means of the conductors 25, 32 and S8, the two latter of which are supportedin the slot '31 in the insulating base by meansY of a ggralityof conductingscrcws 53, 53 and Lessors The current to the threaded shell contacts 14 is supplied through the conducting member 13 which has electrically connected thereto by means .of a binding screw' 54 the conductor 26, as shown at 55 (Figs. 3 and 5).

The insnlating base 12 has a raised or head ortion 5o substantially centrally thereo which has an annular sloping portion 57 extending downward. a short dis-` tance from theupper surface thereof. A plurahtyof center-contacts 58 59, 60 and 61 aresuitably secured on the hcadportion of said insulating base, said center contactsv ger 59 which engages the insulated portion of the brush carrier when the switch is in a position as shown in Fig. 2, or cnages the'hrnsh v38 when the, switch is in on position. A screw 62 secnres said cen- \ter Contact 58 on the insulated base. An insulated block 63 is disposed between the hook portion ot the centercontact 58 and acts as a support for said Contact' when the contact portion of a translating device en ges the same. l,

The center contacts 59 and 60 are electrically connected by means of a conducting bar 64, said bar and cent-:ir contacts being secured on the opper surface of said insulated head 56 by a plurality ot' screws 55. A spring contact iinger 6 is alsosecnred to said head portion by one ot said screws and extends downward and contacts eitherv the insulating portion of the brush carrier' when thevswitch is in oit position or the conducting brush when the switch is in on positlon. This articular switch, therefore,

lli)

controls two lig ts: The center Contact Gi. y

is connected with a switch mechanism in a like manner, the switch in connection there with7 however, controllingr but one iight.

The circuit as outlined in the description will now be followed; VThe current flows from the conductor 25 through any of the switches which may be in on position h means of either conductor 32 or 33 throng the spring contact fingers of the-switehto the respective center contacts, 'then through the translating-devices in contact therewith, throngh thesh'll contacts 14, the-metal com ducting member 13,., and hut through the conductor 28 secured. at 55 to said conduct Y TQi-lrrffl"inenaher. l

Assuming that the switch controlling the vertically disposed bulb Within the howl 19 is the only one in, on position, the circuit aannam would then be fromy the Vconductor through binding plate' 4l, the bracket 40 formed integral l therewith, the arm 43, brush 4t2, spring; contact finger 59 and the center contact 58 from where it will pass through the lamp filament to the threaded shell contact 14, the metal conducting member 13, and out through the conductor 26. lVhen the above mentioned switch is in on position and the remainin switches are oth the diffused light is o tained due to the vertically disposed bulb being within the translucent bowl.

Assuming now that the switch controlling` two lights is in on position, the circuit would then be 'from ,the conductor Q5 through the binding plate al, screw 53, con-v ductor har 32, screw 53, through the switchA l and the `conducting,r member 13 out through the conductor 26. -l

The current will pass through corresponding elements in connection with the remaining switch except that an additional conducting bar 33 is disposed between the 'Pscrewsil and 53" to transmit the current to said last mentioned switch mechanism which controls but one light. .i
